ABSTRACT:
A feeding unit for feeding an element to a treatment unit of a machine tool, in particular for feeding a rivet to a riveting unit, has a gripping element provided for the fastening element for the automatic take-up of the fastening element from a supply unit and automatic feed to the treatment unit. The gripping element is disposed on a rotary element rotatable about an axial direction, and at least one electromagnet is provided which is configured in such a way that a torque acting on the rotary element is generated by a magnetic force.
